The invention relates to`improvements in a liquid fuel oil burner with adjustable baille plates inside the pot or burner by which the flame may be controlled by raising or lowering the baiiles and the sleeve arranged outside of the burner which sleeve regulates the air supply to the burner and gives aperfect combustion on a low, medium or high flamewithout carbon or smoke.

In order that the invention maybe clearly understood, reference is to be had to the accom--l panying drawing in which Figure 1 illustrates an elevationalview of the heater with combustion chamber and burner `Figure 2 shows the front of the heater cut away, showing baiiies and flame spreader with controls connected to the outer sleeve to which the adjustable baiiles are bolted. Figure 3 is a plan view of the baffles with opening in center. Figure 4 shows another view of the baiiles with ame 'spreader and studs to spacel the bales and to which the bales are fastened. Figure 5 shows control by means of which the baffles are raised and lowered and locked to hold the baflles in any position. Figure 6 is a plan view of the damper which prevents the heat from rushing up the chimney.

Figure 7 shows plates which fasten to the outside of burner where brackets pass through to,

connect baiiies to the sleeve on the outside of burner.

Figure 8 shows the burner `with perforations through which the air passes from the outside to inside of the burner.

In Figure 1 No. I is the outside sleeve to which bailles I4 are fastened. No. 2 is the rod that connects sleeve I, to control in Figure 5 by which baliles I 4 and sleeve I are raised and lowered. I2 is the combustion chamber. Il is the burner. I8 shows opening for oilpipe connections. I9 shows plate riveted to burner. 5 is control wheel for raising or lowering baiiles Hand sleeve I. I is a tube that passes through combustion chamber IZVand fastens in place with lock nuts' on the inside and outside combustion walls I2. 'I'he numeral II indicates the rod that passes through tube III to which gears 3 arefastened, which gears engage `teeth 4 of connecting rods 2. Gear 6 is stationary and is fastened to frame 8. Rod II which passes through tube Ill has square ends on which gears I are fastened so that they will rotate with rod l I. Gears E and 1 form a ratchet an'd are locked in place with spring 9. When control wheel is pulled outward from chamber I2 it' releases gear 'lfrom gear 6, then the control wheel 5 is turned, this will raise or lower baffles Il and flame spreader I5 and sleeve l. I3 is the waste damper to keep the heat from rushing up the chimney and it is mounted in the combustion chamber i2 just below the smoke outlet pipe 2li. Baliles It are fastened to sleeve I on four sides with arms 2l. Arms 2l pass through slit 2i) in plate I9 on burner Il and connect to sleeve I to which they are bolted. Plates I9 have their edges bent out wardly so as to form a guide in which cover 22 slides vertically. As baiiies I4 and sleeve l are raised or lowered cover 22 covers up slit in plate I9 so that the burner Il can not take in air at.

this point. 23 shows a small 4opening in cover ZZ large enough to admit arms 2l.

Sleeve l controls the air inlet in burner Il in connection with baiiles I4 by being able to con trol the air inlet in burner Il and being able to raise the bales increasing the lcombustion space in the bottom of burner, itcan be operated on much less fuel consumption and still have a clean re with perfect combustion. This burner can be operated at any stage, low, medium or high ame, raising sleeve I and baiies I@ according to how muchfuel is turned into the burner I1 which gives it the proper amount of air through the small holes in burner I'I. This will always burn without forming-carbon in burner I1 and combustion chamber I2. 4The height of flame can be increased and .decreased without increasing or decreasing fuel consumption by raising or lowering sleeve I and battles I4. I am aware that prior to my invention, pot type oil burning space heaters have been made with stationary baiiles without adjustments while the burner is in operation except for turning the fuel on and oil. i i

I claim:

1. In an oil burner. a cylindrical body portion comprising a lower burner chamber and a combustion chamber above the burner chamber, said burner chamber having a plurality of openings formed in the wall thereof, movable deflector plates mounted within the burner. chamber. meansfor securingthe deector plates in spaced relation with each other, a sleeve movable over thebody portion and openings, regulating 'the passage ofvair into the burner chamber, and means for adjusting the deector plates and sleeve simultaneously. I

2. In an oil burner, a cylindrical body portion comprising a lower burner chamber and a comi bustion chamber above the burner chamber, said burner chamber having a plurality of openings formed in the wall thereof, superposed deector plates spaced apart and having central aligning openings, mounted within the burner chamber, means for connecting the deector plates, a vertically movable sleeve mounted for sliding movement on the body portion and adapted to control the passage of air to the burner chamber vthrough said openings, and means for operating the deflector plates and sleeve simultaneously.

3. In an oil burner, a cylindrical body portion comprising a lower burner chamber and a combustion chamber above the burner chamber, said burner chamber having a plurality of openings formed in the wall thereof, superimposed deflector plates arranged in spaced relation with each 'other and having aligning central openings through which products of combustion pass upwardly to the combustion chamber, a spreader plate spaced from the uppermost deflector plate and overlying the opening thereof. a sleeve movable over the body portion and adapted to regul' late the quantity of airpassing into the burner chamber regulating combustion within the burner chamber, and means for moving the defiector plate and sleeve simultaneously.

4. In an oil burner, a cylindrical body portion comprising a lower burner chamber and a combustion chamber above the burner chamber, said burner chamber having a plurality of openings formed in the wall thereof, deflectng members within the burner chamber and adapted. to control the passage of products of combustion to the combustion chamber, a sleeve operating over the burner chamber and adapted to regulate the quantity of air passing into the burner chamber, and means for moving the sleeve and defiector means simultaneously.
